Thanks for your suggestions, Chaley.
I checked
- the metadata database file is 3.7MB, so I doubt if it's a new file containing metadata for only the one book I added yesterday
- all the book files are in my Calibre Library
- the metadata file had read and write permissions (not execute) for my username
- ~/Library/Preferences is all read/write/execute for my username, and I can't find any Calibre preferences in /Library or in either of the Application Support locations
So I set the metadata file to read/write/execute for my username, then reopened Calibre, but I still got a list of only one book.
Code:
calibre-debug -g
-bash: calibre-debug: command not found
Oops.
It looks like copying things over might not have worked entirely. Or does Calibre need a different $PATH?
